MENDEL HOWARD, OF NE? YORK, N. Y., ASSIGNOR OF ONE-HALF TOJAMES E.CAMPBELL, OF HAMILTON, OHIO, AND QUINTON CORYVINE, OF NElV ROCHELLE,NElV YORK.

MATRIX-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 441,564, dated November25, 1890.

Application filed March 29, 1888- Serial No. 268,803- (No model.)

To all whom it may concern.-

Be it known that I, MENDEL HOWARD, a citizen of the United States,residing at New York, in the county and State of New York,

have invented newand useful Improvements in Matrix-Making Machines, ofwhich the following is a specification.

This invention relates to machines for making type-molds or matrices fortype-foundin g;

[o and by means of this invention the matrixmaking machine can be madecompact and simple in construction, as set forth in the followingspecification and claim, and illustrated in the accompanying drawings,in

I 5 which- Figure 1 is a section of a matrix-making machine in the planew :r,-Fig. 2. Fig. 2 is a section along y y, Fig. 1. Fig. 3 is a planview of a type-carrier and guide-plate on a larger scale than thepreceding figure. Fig.

4 is an end view of Fig. 1.

In the drawings, the letter A indicates a base or support. A treadle Bconnects with a link C,from which a lever Z, Fig. 4, extends 2 5 tolever D, and when the treadle B is depressed the levers Z D are actuatedso as to depress the plunger E. A stop F prevents excessive motion ofthe lever D. When the treadle B is depressed, the levers Z D are 0 movedto actuate the plunger E and make it strike a punch H. When the treadleB is released, the spring G carries the treadle B and plunger E back tothe position shown in Fig. 1. In place of the spring G the spring a 3 5can be used to restore the plunger E, and the spring G can be replacedby a string which will limit the descent of the treadle B.

The punches H are subjected to the action of springs J acting onshoulders I on the 0 punches. The punches rest in a punch-carrier K, andsaid carrier is adapted to slide in guides or ways L M, Fig. 1. As thecarrier K has arms I) resting loosely between the guides L M, saidcarrier can be moved in any direc- 5 tion to bring any desired punchunder the plunger E.

' The punch-carrier has an arm N, provided with an index 0. Aguide-plate P has depressions or stops Q, corresponding in position tothe arrangement of the punches H. As the index 0 is moved to anydepression Q in the guide-plate and then pressed into said depression,the punch-carrier is moved and secured in position to hold thecorresponding punch H in position to be actuated by the plunger E. Whenthe index 0 is released, said index is moved out of engagement with therecess Q by a spring (not shown) arranged in any suitable well-knownway. The punchcarrier K is moved either by the operator manipulating thearmsb that support the punch-carrier K or by the operator moving theindex 0 in the direction in which the carrier K is to move.

The matrix material R to be molded is secured in a support S resting onthe frame A.

A screw T, having a hand-wheel U,is adapted to move the support Stransversely, and a screw V, having a hand-wheel WV, is adapted to movethe support S longitudinally. The screws T V enable the support S to beadj usted so as bring any desired portion of the matrix material It tothe punch H, which is to be actuated by the plunger E. When all partsare in the desired position, the tre:d(le' B is depressed, thus forcingthe plung -E against a punch H, and forcing said/punch against theresistance of its spring J into contact with the matrix material R. Thematrix material thus receives an impression corresponding to thecharacter or letter of the particular punch H which is forced againstthe matrix material.

By having the punch II and stops or depressions Q arranged in a seriesof rows or lines, as shown, a considerable number of punches and stopscan be arranged in a limited space, thus enabling the device to be madecompact. Gibs X and set-screws Y, Figs. 1 and 2, are shown adapted tomake the support S travel snugly back and forth, since by tightening thescrews Y each of the gibs X can be forced against a side of a way forthe support S, so that said support will not shake or travel loosely insaid ways.

What I claim as new, and desire to secure by Letters Patent, is-

The combination, with the frame A, having opposite guides L M, of thepunch-carrier K, the punches, and a support for the material to havingrigidlyattached arms I) b, sliding to be molded, substantially asdescribed. lengthwise between the guides, and in their In testimonywhereof I have hereunto set sliding movement carrying the punch-carrier,my hand and seal in the presence of two sub- 5 a guide-plate P forguiding and holding the scribing Witnesses.
